Thanks for your advice. But from my point of view, there is a problem with this solution.

Designing client_start like this breaks down the regular call of the parent's client_start. In OO design, the OBJECT constant contains 0 and the KERNEL constant contains 1. If I remove $self from @_, KERNEL still refers to 1 and I cannot access it utilizing my ($self, $kernel, $heap, $session) = @_[ OBJECT, KERNEL, HEAP, SESSION ];.

But I found the solution in http://poe.perl.org/?POE_Cookbook/Object_Methods:

Disadvantages

    * Some people don't like OO.
    * Because @_ has so much in it, one has to do silly 
      things like shift(@_)->SUPER::subroutine(@_); 
      to call parent POE-related methods.

With this rational to access overwritten parent methods, client_start can keep my ($self, $kernel, $heap, $session) = @_[ OBJECT, KERNEL, HEAP, SESSION ];.

The solution is in sync with your advice and with holli's very general comment, too. Problem is, that both advices do not really reflect the special POE object design :-)
